Hi Brad,
Oh, interesting! As Ben said, we do now have an issue for this, but I'm
tempted now to look into if that is an easy fix. At the very least,
I'll update the issue with that information.
Thanks,
Lydia

Hi Tomsy and Lydia --
I agree that someone should open a GitHub issue against this. Note
that if halt() is used instead of exit(), the compiler does not issue
a similar warning, suggesting that we already have logic that can
handle such cases, but that it just doesn't cover exit() for some
reason... So it may also have a five-minute fix (in which case no
issue would need to be opened).

Hi!
Without further context, I can't be certain, but I suspect that your
inline proc has a path through itself with the exit() branch where no
return statement is present, i.e.
inline proc exiter(x: int): int {
if (x > 10) {
exit(0);
} else {
return x;
}
}
I verified locally that an inline proc can use exit() when the
function either:
a) doesn't expect to return anything or
b) has a return statement that is reachable, even through a branch
with exit() in it.
So you could insert a bogus return statement after the exit() to get
around this issue.
It seems potentially inappropriate to me that exit() is not
recognized as okay when ensuring that a function will always return.
Do others agree? Would you like to open an issue on that? Or shall I
do it for you?
Thanks,
Lydia

Dear all,
I was trying to exit from an inline proc using exit(). My intention
was to exit from the entire program (similar to exit() in C). I get
the error
"error: control reaches end of function that returns a value"
Can some one explain it.
How can I exit from such a function?
